Food Habits

At present, there is limited information regarding the diet and feeding habits of Mesoplodon perrini. However, it is suspected that these whales feed primarily on squid and some fish, as do many other ziphiids. This is supported by gut content analysis of two of the type specimens. One contained the eye lens of a squid, and the other contained two squid beaks (identifed as Octopoteuthis deletron) and unidentified vertebrate parts.
